PUMP.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed March 221919. Serial no. 284271.

To all whomit. may concern:

Be 1t knownth-at I, HnNnY A. Bnonnonx, a citizen of the Un1ted 'States,.residing at Reedsville, in. the: county of Manitowoc and and arrangementof parts which will be more fully described in the followingspecification and set forth with particularity in the claims appendedhereto,

In the drawings:

Figure 1 represents a side elevation of a pump illustrating theinvention applied to use,

Fig. 2 represents an enlarged longitudinal sectional view through thesupplementary pump cylinder, and

' Fig. 3 represents a transverse sectional view through thesupplementary cylinder.

Referring to the drawings in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates the supporting base or flange carried by the hollow pumpstand 6 provided with a 1101- low extension 7 i for connection with apipe whereby the water pumped may be conveyed to any desired point. At apoint op-' posite the extension 7 the stand is provided with the usualoutlook spout 8 havinga valve 9 therein for controlling the passage ofwater therethrough and the upper terminal of the stand is finallyrestricted and provided with a capv 10 through which the pump rod 11extends. The upperterminal of the rod is connectedwith the pump handleor lever 12 pivotally supported in a racket 13. v

Beneath the platform on which the stand is supported is arranged thebarrel 15 which is secured at its upper terminal in the stand and isconnected at its lower terminal with the cylinder 16 in which isarranged any preferred type of pump operable during reciprocation of therod-'11 to elevate a. column of water in the barrel.

The barrel 15 is divided intoitwo sections at a point below the platformand the upper section 1S connected with a cap 17 while the lower sectionis connected at its upper end with a cap 18, the caps 17 and 18 formingthe terminals of asupplementary pump housing 19.

The cylinder is provided with internal longitudinal ribs 20 arranged inpair and supporting a supplementary pump cylinder 21 through which therod 11 extends. The

lower end of the supplementary cylinder is open and the upper endthereof is restricted in diameter and fitted or otherwise connected witha tubular housing 22 which extends upwardly through the barrel 15, stand6 and is attached to and supported by the cap 10.

Within the cylinder the rod 11 is provided with a stop collar 23constituting an abutment for the piston 24 carrying a flanged packingring 25 secured in position upon the rod by a nut 26 threaded orotherwise secured thereon. The flange of the packingring 25 is arrangedso as to prevent thepassage of water upwardly past the piston into thetubular housing 22 and the head enters the cylinder through the loweropen end thereof. Drain pipes 27 are connected with the restricted upperportion of the supplementary'pump cylinder and extend through the wallof the housing 19 and are designed to permit the water which might leakpast the ring 2-5 and in through the tubular housing 22 to flow backinto the well In operation, during the up stroke of the pump rod 11water is lifted into the cylin der 16 of the main pump and during thesubsequent down stroke of the piston is forced upwardly through thebarrel 15.

When the column of water in the barrel necting the adjacent terminals ofthe barrel 110 sections, a supplementary cylinder arranged inconcentrically spaced relation to the housing, a tubular housingextending upwardly from the supplementary cylinder through the barreland receiving the rod, a supplementary piston carried by the .rodrecipro-.

cably mounted in the supplementary cylinder and spaced supporting ribsextending from end to end of the supplementary cy].-' inder andconnected With the housing for ing a cylinder and rod, a sectionalbarrel connected With the cylinder, a'housing connecting the adjacentterminals of the barrel sections, a supplementary cylinder arranged 1nconcentrically spaced relation to the housing and having a restrictedupper terminal, a

tubular housing connected with the, upper i restricted portion of thesupplementary cyltween the piston and supplementary cylinder Wall,spaced supporting ribs extending from end to end of the supplementarycylinder and connected with the housing for rigidly maintaining thesupplementary cylinder in concentric relation thereto throughout itsentire length, anddrain pipes connectedwith the upper restricted portionof the supplementary cylinder abovethe piston therein and extendingthrough the housing to assist in maintaining the supplementary cylinderin position.

In testimony whereof, I aflix my signature hereto.

HENRY A. BLOEDORN.
